wr 0.1.3

wr is a simple, lightweight module that provides random choice based on weight

wr is a weighted random implementation in Python.

wr.choice can be fed both mappings (such as dictionaries) and sequences of pairs containing what to return and a integer representing their respective weight. It returns a the key of in case of mappings based on the weights defined in the key’s corresponding value.

The key can be anything hashable but the weight must be a integer.

Optionally you may feed wr.choice with a sequence of pairs.

Example

>>> import wr

>>> data = {'cat': 60, 'dog': 30, 'bird': 10}
>>> animal = wr.choice(data)
>>> print animal
cat # well, the cat had a good 60% shot at it.
